Answer:
Let coefficient of linear and area expansion be α a n d β respectively. where ∆ T is change in temperature. For simplicity let us consider the case of square of side L. Therefore, coefficient of area expansion is twice the linear expansion.
Answer:
Knowing that the temperature at sea level (0 m) is 20 ° C, we will calculate the air temperature at. The altitude of 3500m.
According to the vertical thermal gradient, the air temperature decreases by 6 ° C at 1000m alt.
1000 m .... 14 ° C (20-6 = 14)
2000 m .... 8 ° C (14-6 = 8)
3000 m ... 2 ° C (8-6 = 2)
3500 m .... - 1 ° C (2-3 = -1
Explanation:
The bark helps to increase water loss in the plant is the best explains why the list is incorrect. The thick cuticle on leaves helps to retain water in the plants.
<h3 /><h3>How do plants protect themselves?</h3>
The plants can protect themselves through an intact and impenetrable barrier composed of bark and a waxy cuticle. This is also protecting the from herbivores animals.
Other adaptation include shells, thorns that are modified branches, and spines that are modified leaves.
Thus, option B is not correct.
